The Rev. Robert H. Schuller announced that his ministry's multimillion-dollar Maui property has been sold as a "family retreat" to former U.S. Treasury Secretary William E. Simon. Schuller, who did not reveal the price tag for the 43-acre retreat, told his congregation in Garden Grove's Crystal Cathedral that the transaction "has poured multiplied millions of dollars into a $23-million Family Life Center." Schuller had been seeking a buyer for the prime acreage for more than a year.
